HIDE FINISHING APPARATUS William B. Quinn, Philadelphia, Pa.

Application July 6, 1935, Serial No. 30,108

6 Claims. (01.51-12) This invention relates to' apparatus for finishing-hides and is concerned primarily with finishing machines which include, as a finishing element, an abrading wheel.

At the present time, operators of the now known types of finishing machines are experiencing considerable difliculty in maintaining the hides in proper engagement with the abrading wheels, this condition being largely due to the necessity formaintaining an appreciable degree of tension on the skins and at the same time maintaining-themspread out, flatly on the abrading surface. a

With the-foregoingin mind. this invention has infview as an"important object the provision of hide finishing apparatuswwhichf includes an abrading wheel with which are associated instrumentalities for maintaining a hide in operative engagement with the abrading wheel underany desired degree'of pressure.

Another end in view is the, provision of instrumentalities of the character above noted which include, as anessential element, an endless belt having a surface positioned in close proximity to the abrading wheel and which surface is movable in the same direction as the corresponding surface of theabrading element.

A somewhat more detailed objective is the.

provision of an endless belt of the character above noted which is pivotally mounted at one end and which is movable on said pivot to vary the pressure which is applied towhides positioned between the said belt and theabrading wheel.

Yet another object in view is to provide, in a hide finishing machine of the type-above noted, an abrading wheel and a pressure member in the form of an endless-belt, together with driving. mechanism therefore which is effective to drive the wheel and the belt at the same surface speeds. In carrying out this idea in a practical embodiment, I propose. to drive both the belt and the wheel from a common drive shaft so that the inter-relationof their respective speeds is at all times assured.

A further object of the invention is to provide, in ahide finishing machine including an abrading wheel, pressure instrumentalities which are adjustable to accommodate the particular requirements of any individual operator and which instrumentalitiesare effective to apply varying pressures on the hides being finished.

Various other more detailed objects and advantages are, associated with the carrying out of the above notedobjectives in. a practical working apparatus. i

ing the belt so that a corresponding pressure may 10 be implied to the hides. Other detailed parts of the apparatus include the driving connections, tensioning means .for the endless belt, and the yielding means for normally maintaining the belt spaced from the wheel.

For a full and more complete understanding of the invention, reference may be had to the following description and accompanying drawing wherein: t

Figure l is a plan view of a hide finishing J machine made in accordance with the perceptsof this invention, and

Figure 2 is a View in side elevation of the machine shown in Figure 1.

Referring now to the drawing wherein like reference characters denote corresponding parts, the apparatus constituting the machine of this invention is shown as mounted on a supporting table, referred to generally by the reference character A. This table includes upstanding legs I which may be secured to a floor or similar surface, as indicated at H, and at their upper extremities thelegs l0 carry a table top designated I2. A counter-shaft is shown at [3 as being rotatablymounted on the under surface of the table top l2 and this counter-shaft I3 is driven from a suitable power source, such as the electric motor indicated at I 4, which is connected to the counter-shaft l3 by a driving belt l5. Obviously, the counter-shaft l3 could be driven from any power source desired.

An abrading wheel is shown at I6 and may take the form of any of the well-known wheels of this character. This wheel I 6 is shown as being non-rotatably mounted on a shaft I! that finds bearing in brackets I8 mounted on the under surface of the table top l2. The latter is provided with a cut-out portion to receive the wheel l6, which wheel is shown in dotted lines in Figure 1.

A pulley I9 is drivably carried by the shaft I! and from this pulley l9 extends a driving belt, which is crossed as shown in Figure 2, andiwh 'q belt extends to a pulley mounted on the-100 11 3,

nt O

shaft l3. It is evident that u on moveme the belt |5 in the direction indicated by the arrows on Figure 2, the counter-shaft l3 will be driven in a clockwise direction which, due to the crossing of the belt 26, will drive the abrading wheel IS in a counter-clockwise direction. as shown by the arrow on the wheel 6. Upstanding from the table top I2 is a pair of spaced legs 2| which may be secured to the table top l2 in any preferred manner, such as by the pedestals shown at 22 which may be bolted to the table top l2. A pair of spaced side bars 23 extend forwardly of the table from the upper extremities of the legs 2|. Asshown in Figure 2, diagonal bars 24 serve to brace the connection between the legs 2| and bars 23 so as to insure the rigid mounting of the latter. In this connection, it is notable that this invention contemplates the adjustment of the angle between the This adjustment may be.

, which are drivably carried by the shaft 28. The

coun'ter shaft l3 has non-rotatably mounted thereon, a pinion 3| and a chain 32 extends from the pinion 3| and gear 29 to provide the driving connection between the counter-shaft l3 and the shaft 28. a 1

At the forward extremities of the side bars 23,

a shaft 33 extends thereacross, and is retained in operative position in'any preferred manner, as by'the nuts indicated at 34. This shaft 33 carries a pair of pulleys 35, corresponding to the pulleys'30 on'th'e shaft 26, and a pair of driving belts .36 extend from the pulleys 30 and 35 to drivably connect the shaft 33 with the'shaft 28. A roller 31 is carried by the shaft 33 for a purpose to be hereinafter described.

5 Pivotally attached to the shaft 33 is a framework comprising side bars 38 and crossbars 39, 46, 4| and 42. The side bars 38 may be angle bars and their ends are cut away as shown at 43 to accommodate the roller 31. These ends are of a curved construction as shown at 44 in Figure 2 and the extremities of these curved parts 43 are provided with openings which receive the shaft 33. At the end opposite to the shaft 33, the side bars 38 are of a similarly cut away and curved construction and carry a shaft 45 which in turn carries a roller 46.

An endless belt which may be made from any suitable fabric is shown at 41 as extending from and about the rollers 31 and 46, and this belt 41 is driven incident to rotation of the shaft 33. Upon reference to Figure 2, it will be noted that as the belt 41 is driven from the counter-shaft |3 by the driving connections, including chain 32, shaft 28, belts 36 and shaft 33, the under surface of the belt 41 will be driven in a direction corresponding to that in which the upper surface 'of the abrading wheel |6 is driven. Means for maintaining the proper tension on the belt 41 between the rollers 31 and 46 so as to take up any slack in the belt, is shown in the form of a roller 48 which is carried between arms 49 that are'in turn aiiixed to the crossbar 39 as indicated at 5ll,

A pair of leaf springs is shown at 5| as normally urging the roller 48 downwardly so as to M and 42, as shown in Figure 1.

free ends of the arms 54, as indicated at 55, is

take up slack in the belt 41. Extending across the top of the side bars 23 is a yoke member 52, and a spring 53 is connected at one end to the top of the yoke member 52 and at its other extremity to the crossbar 4|. This spring normally maintains the framework carrying the belt 41 in an upraised position in which it is spaced from the abrading wheel l6.

Means for urging the framework and belt 41 downwardly against the influence of thespring 53 is shown in the form of a pair of arms 54 which are interlocked with the crossbars 40, 45 Connected to the a pair of cables 56 which extend downwardly through openings in the table top I2 about a pair of pulleys 51 and along the under side of the table top |2 to a point where they pass about another pair of pulleys 58 at the forward end of the table. The ends of these cables 56 are anchored to a'treadle designated 59 which may be pivotally mounted as shown at 60. on the front legs Hi. It is evident that upon the operator urging the treadle 59 downwardly by the use of his foot, the cables 56 will be pulled to cause the corresponding downward movement of the frame and the'belt 41.

Intermediate the upper and lower surfaces of the belt 41, there is shown a backing member 6| which is provided with an arcuate surface 62 that corresponds in curvature to the upper surface of the abrading wheel Hi. This backing member 6| may be pivotally carried by arms 63, which depend downwardly from the crossbar '40. This backing member 6| serves to insure a solid backing for the application of pressure to skins being finished.

In the operation of the above described apparatus, the motor I4 is started whereupon the abrading wheel l6 and belt 41 will be driven in the direction indicated by the arrows. Without the application of pressure to the treadle 59, thebelt 41 is spaced from the abrading wheel. A hide, such as a sheep skin, which is to be finished may now be inserted between the abrading wheel l6 and belt 41, whereupon the operator steps on the treadle 59 to apply a desired amount of pressure to the hide. The latter is firmly held by both hands of the operator so that it may be moved in all directions across the abrading wheel to have the proper finish applied thereto. Upon release of the foot of the operator from the treadle 59, the spring 53 returns the belt 41 to its upraised position.

While a preferred specific embodiment of the invention is herein set forth, it is to be understood that I am not to be limited to the exact constructions illustrated and described because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.
